APPARATUS FOR MANUFACTURE OF GAS.

SPECIFICATION forming part of 'Letters Patent No. 541,540, dated June 25, 1895.

Application filed November 12, 1894. Serial No. 52 92 (No model-l To all whom it may concern..-

Be it known that I, LUKE M. HEERY, a citizen of the United States, residing at Monson, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Apparatus for the Manufacture of Gas,of which the following is'a specification, reference being had to the accompanying sheet of drawings.

This invention relates to apparatus for producing hydrocarbon gas and has for its particular object the improvement of the retort employed to volatilize and distribute the oil used in the production of such gas.

To more readily explain my invention I have annexed hereto 2. sheet of drawings, illustrating such portions of a gas producing apparatus as are immediately connected with said invention.

In the drawings, Figure 1 is a verticalcen tral sectional view of a furnace and connected superheater or generator. Fig. 2 is an elevation, partly in section, of the vaporizingchamber, which forms the leading feature of my invention. Figs. 3 and 4 are respectively plan and edge views of said chamber.

In the production of gases of this class it is particularly desirable, in fact necessary, in order to produce the best results, that the oils introduced shall be thoroughly volatilized or vaporized before being introduced to, and mingled with, the gases arising from the fuel on. the grate and it is also desirable that such volatilized oilsshall be broken up, separated, and discharged from the retort at various points rather than from a single large orifice and, to accomplish these desirable results, I have provided a peculiar, but cheaply produced, retort which I will proceed to describe.

Referring to the drawings, A indicates a furnace as a whole, having a combustion v chamber a, ash-pit b, clearing-outpit c and grate d. Surrounding the combustion chamher and connected with the top thereof, is an annular chamber 01 whose lower portion is connected by a flue or pipe B with a superheating or regenerating chamber. 0, which latter may be of any approved construction. The ash-pit chamber b is also connected, by a flue D, with said superheating chamber 0.

f indicates an air pipe leading from a blower and having suitably valved discharge pipes f'f that enter, respectively, the combustion chamber and ash-pit. By means of this air pipe and its valves the products of combustion of the furnace may be discharged through the annular chamber d and flue B into the superheater 0 or such products may be blasted back through the ash-pit and fine D into said superheater, this constructionbeing however a common one in this class of apparatus, and forming no part of my present invention.

h denotes a steam pipe leading from a boiler located at any convenient point, said pipe having one branch h V (with valve 71?) that dis charges into the ash-pit, and another branch h (with Valveh) connecting with an oil pipe 1' that discharges into a retort formed as a hollow disk and supported in the upper part of the combustion chamber a} The described oil pipe 2' discharges throughthe upper wall of said retort, and said upper wall is provided with a large number of comparatively small openings 10', as clearly seen in the several drawings.

When the apparatus is in service the disk retort, being so located as to receive the direct influence of the caloric products of-combustion, is highly heated and oil discharged into said retort, through pipe 2', is immediately raised to a correspondingly high temperature and volatilized. In'its efforts to escape (under pressure) such volatilized oil is then discharged through theseveral openings k and at once mingles with the surrounding gases arising from the fuelon the grate.

The efiect, in practice, is a constant dis charge of oily vapor, from each of the openings k, in such limited quantity as to most readily commingle with the gases arising from the fuel on the grate, thus producing a more satisfactory result than when the oil is discharged directly from a pipe corresponding to pipe 1'.

The disk retort It has a central opening with an annular ledge or rib 10 upon which rests the lower end of a cylindrical chute m through which coal may be introduced into furnace at and, to close the upper end of said chute, I provide a cap or cover m of disk form that is held in place by some practical form of fastening. As here illustrated said cover is fastened by means of a yoke 12. whose ends hook under the flanged upper end of chute m, the yoke being provided with a clam ping screw 0 Whose end abuts the cover m, as clearly shown in Figs. 1 and 2 of the drawings.

From the foregoing description. the operation of my improvement is obviously as follows: The chamber at having been charged with a proper amount of fuel, and the latter ignited, the heat arising therefrom, will so heat the retort chamber 70 as to thoroughly vaporize and mix the oil and steam entering said chamber through the pipe 2. The vapor thus generated will be forced through the openings 70' in small jets, which enables it to readily combine with the gases arising from the fuel on the grate (Z. This combined product then passes by Way of the annular chamber d, and pipe B to the superheater 7, from whence it is finally distributed.

My described vaporizing retort may be cheaply produced, does not interfere with the functions of other parts of the apparatus, and is a valuable aid in the process of gas makin Having described my invention, I claim-- 1. In combination in and with the furnace of a hydro-carbon gas apparatus, a vaporizprovided with a central opening and having an annular flange or lodge, a cylindrical chute Within the opening and resting upon the aunular flange, a cover for the chute, a regenerating furnace communicating with the first mentioned furnace, and means for supplying the retort with oil and steam, substantially as set forth.
